Fixes a bug pointed out by @weaversa:
https://github.com/GaloisInc/cryptol/issues/127#issuecomment-64464455
In addition to the other search path changes in #127, we now will add
the directory containing files to be loaded to the search path. This
applies to:
- files loaded with a command line argument, like in the original
comment
- arguments to `:l`, so for example `:l examples/DES.cry` would work
- batch file arguments, so for example running `cryptol -b
/some/path/bar.cry` adds `/some/path` to the search path.
When `:set mono-binds=on`, any local definitions lacking type
signatures will not be generalized (i.e., will be monomorphic). This
reduces what is in most cases unnecessary polymorphism that can give
rise to constraints that are difficult to solve. This also improves
the performance of the Cryptol interpreter by lifting many polymorphic
type applications out of the inner loops that are commonly defined as
bindings in `where` clauses.
The flag is on by default in the Cryptol REPL, and in most cases makes
it possible to leave out more type signatures in `where` clauses than
before. However, some programs really do rely on inferring polymorphic
types for local variables; in this case adding an explicit polymorphic
type signature to the local binding in question will make the program
typecheck.
